(2008 Vintage) Considered one of the rarest wines of the world, true ice wines are made from perfect grapes left on the vine long after traditional harvest. The weather has to cooperate, too, with a slowly cooling late fall. A three - four day hard freeze with temperatures in the teens prepares the grapes for harvest. These grapes were picked in a blinding December snow storm by 12 hardy souls. The grapes were then crushed outdoors - they cannot be allowed thaw for true ice wine. This process can take days of pressure, extracting about one drop of concentrated juice from each grape.
